I disagree. AMD may be making strides in AVX2 / 256-bit compute, but Intel is pushing AVX512 very strongly, with Icelake giving support. At very least, the future will be partitioned into AVX2 vs AVX512 performance categories moving forward. AVX512 would be useful for H265 encoding, among other applications. I'd imagine that Intel's mesh network is superior in databases and some other workloads too, compared to the split-L3 cache on AMD's Zen design.
"Single-threaded 64-bit compute" (such as what video games typically do) seems like AMD is reaching parity with Intel soon. At least, Intel hasn't made any big announcements for big IPC or clock-rate gains yet, while AMD is clearly benefiting from 7nm and higher clocks. Its a tough call overall, since Intel has been so silent on the issue. But... one would assume that if Intel actually made big strides in the lab, they'd be bragging about it by now.
So that's why I'm assuming Intel didn't make big strides in "single-threaded 64-bit compute". Because Intel simply isn't talking about it.
Well I was mostly talking about gaming performance. I agree there will be no "parity" as long as there is innovation. There will always be differentiation. I mean, these chips take several years to go from ideas on pen and paper to actual products.
These are different teams of engingeers with different visions of what the market will look like years in advance. They have different strategies, more focus on different market segments, and different targets on the performance vs efficiency curve.
They take different risks, invest more in different bleeding edge technologies, create new innovations of their own, take different approaches to manufacturing, and this is all further multiplied by the work of their different software development teams.
Whether they want to compete directly with or fill in the gaps between existing products, the landscape is inevitably going to look different when they finally come to market, and each of these products will have different strengths and weaknesses.
My prediction is based on AMD, after winning over console makers, hopefully recognizing the importance of PC gaming for mindshare and probably knowing what they need to improve, along with Intel's history of complacency when they're on top.
